INSULATING HANDLE CONNECTION.

SPECIFICATION forming part of Letters Patent No. 05,448, dated June 7, 1898. Application filed April 30, 1897. Serial No. 634,621. No Infid l- To a whom it may concern.-

Be it known that LWILLIAMMCAUSLAND, a citizen of the United States, residing at Taunton, in the county of Bristol and Commonsimilar article with a handle embodying my invention, showing the upper joint in section. Fig. 2 is a modified form of my improved insulating handle connection. Fig. 3 is a sectional detail of my connection. Fig. 4t is a sectional detail of the modification'of my connection.

My invention relates to an insulating handle connection for handles of vessels containing hot liquids to prevent the conduction of heat from the vesselto its handle; and it con sists of a joint having an invisible insulatingwasher against which the two ends of the handle are clamped. Qne of the ends is provided with a cup-shaped end which incloses the insulating-washerand a portion of the end in order to conceal and protect the said washer,

I and the two ends are axiallyjoined by a bolt or pin, as is hereinafter described in detail.

Referring to the drawings, A is the vessel,

and B the handle, a a and b I) being the ends of the handle on each side of the insulation.

0 is my insulating-washer, which I preferably make of cork, and D is the cup-shaped end piece, which is preferably soldered to the end I; of the handle B. This end piece D is perforated at its center and hasat its center the tube d, which projects back into the handle B and is threaded in order to engage with the bolt E, which joins the two ends a and b.

As shown in Fig. 1, the end a of the handle.

is closed except for a central perforation, through which the bolt E passes, its head 6 being inside of the end a, and between the head 6 of the bolt and the closedend a of the handle I place the second insulating-washer F, also, preferably,of cork. When the bolt E is passed through the washer F, end a, washer O, and is screwed tightly into the tube cl, which is joined to the end I), as hereinbefore described, it will be seen that the two ends of the handle a and?) are rigidly joined as shown in Fig. 1.

and at the same time perfectly insulated, as there is no metallic connection, the two ends being simply clamped tightly together against the insulating-washer G. The edges d of the cup-piece D are made to project slightly over the end a of the handle, but do not touch the metal, a slight air-space being left between. Thus a joint is produced which presents the appearance of an ornamental ring about the handle, as shown in the lower joint in Fig. 1, but which is in reality a perfectly, although invisibly, insulated. joint, as hereinbefore described.

After my joint has been made as described and the ends a and I) joined it is necessary to attach the ends a. a to the vessel,which is usually done by soldering. With metals which are poor conductors of heat, such as whitemetal, the heat required for this soldering does not reach the cork washers C andF sufficiently to injure them atall; but when the metal used is silvenor'other good conductor of heat it is found that in the process of soldering the corkin the washers isbadly burned, so that the joint is ruined. In Order to obviate this difliculty, I adopt,when necessary, the modified form shown in Figs. 2 and 4, which embodies the same elements as the first form of joint described-to wit, the centrallyperforated cup-shaped end piece I), secured to the end I), as before, the centrally-perforated end a, the cork washer O, and the connecting-pin E". This joint also presents the same appearance as the first one described,- but possesses the advantage that it can be connected after the soldering is all done, and hence thecork washer is not injured. My connectingpin E is soldered or otherwise metallically secured 'to the end a, which is then solderedto the vessel A. The pin E is then passed through the cork washer O and central perforation in the end piece D,which has been previously soldered to the end I),

and a transverse pin or joint P is then passed H of the members secured to the vessel, the han dle proper, the insulated section and means section having a cup-shaped chamber and carrying the insulating material, the chambered section concealing the insulating material and arranged out of contact with one of the members of the handle, substantially as described.

2. In an insulated handle, the combination of the members secured to the vessel, the handle proper, the insulated section and means for securing the parts together, the said insulating-section having a cup-shaped chamber and carrying the insulating material, the

chambered section concealin the insulating material, and arranged out of contact with one of the members of the handle, and an insulated Washer F, for insulating the securing means, substantially as described.

In Witness whereof I have hereunto set my hand.

WILLIAM MOAUSLAND.
